'intro from stevie nicks' is the definition.
I can't tell whether this definition defines the answer.

'sing about free ride' is the wordplay.
'sing' becomes 'shops' (I can't justify this - if you can you should believe this answer much more).
'about' indicates putting letters inside.
'free ride' becomes 'lift' (as in a lift in someone's car).
'shops' going around 'lift' is 'SHOPLIFTS'.

'with' acts as a link.
